WATER-COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent'N o. 661,192, dated.November 6, 1900. Application filed August 10, 1900 Serial No. 26,466.\No model.)

To all whom it may conoermf Be it known that 1, WILLIAM OSTENDORFF,

a citizen of the United States, and a resident of Union Hill, county ofHudson, and State of New Jersey, have invented certain new and Myinvention is directed particularly to improvements in means for coolingwater by natural aeration and evaporation, caused by allowing the waterto fall in fine drops or streams through the air; and my improvementsconsist particularly in the apparatus which I employ for causing thewater to fall course, thus still more effectually exposing it in thedesired manner.

"In the drawings, Figure 1 is a perspective View of my improvedwater-cooling apparatus. Fig. 2 is a perspective view showing the Fig. 3is a perspective View showing the inside of one of the water-pans; andFig. 4 shows a modification of the same, one side of the pan beingbroken away to show the interior more clearly.

Similar letters of reference designate similar parts in all the figures.

The framework of my apparatus consists, essentially, of four uprights AA A A, with cross-beams B B B to support the Water-pans E E E, the towerbeing suitably braced at the top and foot. The pan-supporting beams arerabbeted on their inner sides, so that the water-pans may sit partlywithin the beamsand be firmly held in place.

The water-pans are made, preferably, of 7 sheet metal and are providedwith perforations through their bottoms to allow the water to tricklethrough. The perforations are placed in lines across the pans, and tothe bottom of each pan is secured a series of in-.

clined flanges F F, which are fastened to the bottom of the pan byrivets g g, passing through the members ff of the flanges F F. The waterfalling into the topmost pan will run through the holes e e 6 with moreor less force, depending on the volume of the water and the pressurewith which it is delivered from the pipe. The drops or streams of waterfalling through the holes e e e will strike upon the inclined uppersurfaces of the flanges F F and running down the inclined 1 surfaceswill fall from the edges in curved 1 lines toward the opposite side ofand into the pan next below. As shown in the drawings, the flanges F Fare inclined from either side of the pan toward its center, so that thestreams of water falling from opposite sides of the pan will cross andintersect, thus breaking up the streams into spray, giving a longercourse to the water in its fall and affording greater opportunity foraeration and evapora tion and increasing the cooling of the liquid. Therows of perforations and flanges of the second pan are at right-anglesto those of the first, so that the water falling from the second pan issprayed to left or right of its previous to the action of the air in itsdescent. This method of arrangement is preferably continued with thesucceeding pans, of which any desired number may be used.

In Fig. at I have shown a modification of the pans wherein the holesthrough the bottom are punched at an angle, leaving an inclined lip orspout h h, whichgives to the escaping water an inclined curved course asit falls. In this formI am enabled to dispense with the use of flangesand to. produce the water-deflectors fromthe material of the pan itself.The angle of these holes may be considerably varied, so that the streamsfrom the different apertures cross and intersect each other, breaking upthe water into drops and facilitating its cooling, as already mentioned.v

In the drawings'I have shown the openings as being inclined toward thecenter from either side; but I desire it to be understood that the angleand arrangement of the defiectingholes may be considerably variedwithout-"departing from the spiritof my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of'the United States, is

1. In a water-cooling apparatus, the combination, with a pan-sustainingframework, of a series of water-pans, each provided with a multiplicityof small apertures in its bottom, and with a series of inclineddeflectors formed of metallic strips secured by one edge to its underside, to cause the water to fall of a series of water-pans, eachprovided with a multiplicity of small apertures in its bottom, arrangedin a series of rows across the pan, and provided beneath each of saidseries of holes with a continuous metallic strip attached to the bottomof the pan through an integral flange and having a free depending edgeinclined toward the center of the pan,

whereby the water is caused to fall from opposite sides of the pan inintersecting curves, substantially as and for the purposes set forth.

3. In a Water-cooling apparatus, the combination, with a pan-sustainingframework of a series of Water-pans, each provided with a multiplicityof small apertures in its bottom arranged in a series of rows across thepan and provided beneath each of said series of holes, with a continuousmetallic strip attached to the bottom of the pan through an integralflange, and having a free depending edge inclined toward the center ofthe pan, whereby the water is caused to fall from opposite sides of thepan in intersecting curves, the deflectors of each succeeding pan beingset at an angle to those on the pan next above, substantially as and forthe purposes set forth.
